MIDIRECORD(N) LOCAL MIDIRECORD(N)NAME
midirecord — tclmidi command to record a MIDI song
SYNOPSIS
midirecord DevID RecMidiID [PlayMidiID [repeat]]
DESCRIPTION
midirecord is a tclmidi(1) command that records events from a MIDI device
and puts them in a MIDI song.
The first argument to midirecord is a MIDI device identifier as returned
from a call to mididevice(n). The second argument is the MIDI song
descriptor of the record song. It should be one returned from
midimake(n) or midiread(n). The third argument is an optional MIDI song
descriptor for a song that should be played while recording. Further‐
more, an optional fourth argument of “repeat” may be specified so the
play song will be repeated.
Recording continues until the midistop(n) command is issued. midiwait(n)
may be used to block until the play song finishes.
All recorded events are put into track 0 of the MIDI song.
RETURN VALUES
midirecord returns immediately with 0 if no MIDI devices are available,
or 1 if one is.
BUGS
The MPU-401 device interface dynamically creates events in the record
MIDI song asynchronously. Since this involves a call to malloc(3) which
is not re-entrant, this is a potential hazard. Until I figure out a way
around this, avoid other calls to malloc(3) while recording. The current
TCL signal synchronizing commands found are not adequate for this task.
